# Algebra

## Topic outline

- Welcome
### Welcome

Our term "algebra" comes from the Arabic word "al-jabr", meaning literally "the collecting of terms".

An outstanding Persian mathematician, Muhammad Al-Khwarismi, who lived about 780–850 CE, gave us this knowledge. He developed the techniques for solving problems that have led to a whole branch of mathematics — called Algebra.

The Arabian mathematicians' contributions live on in the very numbers we use. The Muslim mathematicians from the 9th to the 13th centuries used the numerals 1, 2, 3, . . . , up to 9. The Hindu philosophers gave us the numeral 0, which represents "nothing" (a great need existed for being able to represent this idea with an actual symbol).

Most of the techniques and rules we use in mathematics comes from the start made by the Arabian mathematics, and taken further by European mathematicians in the following centuries. ### Algebra
